Durante os anos 2000 e 2001 foram realizadas coletas sazonais de crustáceos decápodes em dois pontos de um rio na Estação Ecológica Juréia-Itatins, utilizando-se duas metodologias distintas (peneira e armadilha). Comparando-se ambos os métodos de coleta, foram constatadas diferenças quanto à composição e riqueza da carcinofauna capturada, grau de dominância e equitatividade, bem como tamanho e número de indivíduos coletados. Além disso, as razões sexuais de Macrobrachium acanthurus (Wiegmann, 1836) podem diferir dependendo do método de coleta utilizado. Devido à grande variedade de hábitats e hábitos dos crustáceos, pode-se inferir que, para um levantamento qualitativo e/ou quantitativo eficaz e apurado da comunidade de crustáceos decápodes dulcícolas de...

Growth, survival and molting rate in Palaemonetes argentinus Nobili, 1901 were compared under different light-dark conditions. During 80 days, 150 immatures of both sexes (initial mean weight 0.09±0.002g), from Los Padres lagoon, Mar del Plata, Argentina, were maintained in aquaria at 19±0.4°C under three light conditions: 0:24, 10:14 and 13:11 (L-D). They were fed daily on an artificial diet (45% proteins, 17.2% lipids, 7% water, 7% ash). Good weight increment was obtained with the three treatments, finding a positive linear correlation between mean weight and time (0:24, r=0.97; 10:14, r=0.99; 13:11, r=0.98). There were no significant differences in the percentage increment in mean weight among the treatments (0:24, 19.3%; 10:14, 29.3% and 13:11, 26.5%)...

Giri,Federico; Collins,Pablo.

The predator-prey relationship of Palaemonetes argentinus Nobili, 1901 and Culex pipiens s.l. larvae was studied under laboratory conditions. The prawns were separated in two groups, isolated and grouped ones. Mosquitoe larvae were offered to prawns in two forms, limited and unlimited offer to both groups. In the first analysis, values of predation did not differ significantly between males and females of P. argentinus. Predation in 24 h was 14,9 ± 4,2 larvae/prawn. A reduction of predation was observed with unlimited offer for the same hour, during all the experiment. Predation with unlimited offer was higher on the first day than on the second, but returned to high values on the third day, for both groups. In the grouped experiment, predation with...

Felix,Mónica M. L.; Petriella,Ana M..

The molt cycle of the natural population of Palaemonetes argentinus Nobili, 1901 from Los Padres Lagoon, Buenos Aires, Argentina, was studied in relation to age, sex, and environmental factors. A total of 1645 individuals (740 females, 539 males, and 366 juveniles) were collected and analyzed between December 1995 and December 1996. The results indicate that the sex ratio (males:females) remains around 1:1.4 throughout most of the year. The reproductive period extends from September until February (spring and summer), with maximum sexual activity in October and November. Two cohorts originated in the spring and in the summer were differentiated. Ovigerous females arrest their molt cycle during the intermolt period to restart it after oviposition. The...

Casanova, B; Huguet, D; Secretan, S.

A comparison of the skeleton of a successive thoracic segment in various Malacostraca shows the development and growing complexity of phragmal structure. It first appears in some Mysicacea and in Euphausiacea by means of an interarthrodial lamina issued from sternite. In Decapoda, Penaidae, Atyidae, Processidae, Palaemonidae, this lamina is diversified and some elements from pleural origin join it. The beginning of the so constituted wall considerably increases in Nephropidae and becomes ramified.

Lavesque, Nicolas; Bachelet, Guy; Beguer, Melanie; Girardin, Michel; Lepage, Mario; Blanchet, Hugues; Sorbe, Jean-claude; Moderan, Julien; Sauriau, Pierre-guy; Auby, Isabelle.

The invasive oriental shrimp Palaemon macrodactylus Rathbun, 1902 has considerably extended its distribution in transitional waters along the Atlantic and Channel coasts of France during the period 2007-2010. The most probable method of a primary introduction of this species is ballast waters, but passive transport by water currents is also a possible mechanism of colonization (secondary introductions). Palaemon macrodactylus is a powerful invader of transitional waters and these new populations should be monitored in the future to assess any consequences to native species.

On a new species of blackwater prawn, Macrobrachium oxyphilus (Crustacea: Decapoda: Caridea: Palaemonidae), from peat swamps in Peninsular Malaysia

Ng, P.K.L..

A new species of freshwater palaemonid prawn, Macrobrachium oxyphilus spec, nov., is described from highly acidic blackwaters in a peat swamp forest in Selangor, Peninsular Malaysia. The species differs from its nearest congener, M. trompii (de Man, 1898), in having proportionately smaller eyes, shorter scaphocerites, a lesser number of ventral rostral teeth, a more inflated carapace, and less pubescent and more spiniferous chelipeds.

A new species of Palaemon, P. vicinus spec. nov., is described from the tropical eastern Atlantic. The new species is very close to P. elegans Rathke, 1837, under which name it was previously recorded from West Africa. Palaemon vicinus spec. nov. is easily separated from P. elegans by possessing a small tooth on the fifth abdominal pleuron (quadrate in P. elegans) and by having 2-3 rows of setae in the grooming brush of the fifth pereiopod (4-5 in P. elegans). The discovery of the new species amongst material identified as P. elegans further highlights the need to reassess species level characters in the genus Palaemon.

During fieldwork in Raja Ampat, West Papua, Indonesia, in 2007, a pontoniine shrimp, most likely belonging to the genus Anchistus, was collected from a coral boring bivalve of the genus Spengleria. This is the first record of a pontoniine shrimp living in association with a boring bivalve. As it probably concerns a juvenile shrimp, its identity remains unclear. Its affinities with the Indo-West Pacific mollusc-associated genera and with congenerics are discussed.

This study investigates the shrimp found in non-vegetated areas of an estuary of the Amazon River. We ascertained the input of juveniles, species' biometrics and the influence of environmental factors on the abundance of species. The samples were collected monthly, from August 2006 to July 2007, in two places in the estuary, each next to an island. For collecting, we used a manual trawl to perform three hauls per month, totaling 36 samples per site. The abundance of shrimps was estimated as a function of the density of specimens per unit area. We used the Spearman's correlation to test the hypothesis that there is significant correlation between the average of the environmental variables measured and variations in shrimp density. The Kruskal-Wallis and the...

ABSTRACT Population biology, growth and reproductive aspects of the amphidromous shrimp Palaemon pandaliformis (Stimpson, 1871) were investigated in a Neotropical river of northeastern Brazil. The specimens were collected every month from September 2009 to August 2010. Total and monthly sex ratios deviated in favour of males. Von Bertalanffy growth parameters indicated that the females grew more rapidly, reached larger sizes, and had a longer life span than males. We also observed continuous reproductive activity and juvenile recruitment throughout the year. Relations between the number of eggs (fecundity) and body size indicated that fecundity in females increase with size. Compared with previous results, some population biology parameters of the...

ABSTRACT Palaemonid shrimps occur in the tropical and temperate regions of South America and the Indo-Pacific, in brackish/freshwater habitats, and marine coastal areas. They form a clade that recently (i.e., ~30 mya) invaded freshwater, and one included genus, Macrobrachium Bate, 1868, is especially successful in limnic habitats. Adult Macrobrachium acanthurus (Wiegmann, 1836) dwell in coastal freshwaters, have diadromous habit, and need brackish water to develop. Thus, they are widely recognized as euryhaline. Here we test how this species responds to a short-term exposure to increased salinity. We hypothesized that abrupt exposure to high salinity would result in reduced gill ventilation/perfusion and decreased oxygen consumption. Shrimps were subjected...
